How to Make an Offer on a NYC Apartment

In NYC you make an offer by email through the listing agent, and an accepted offer isn't binding until a contract is signed. What to include and how bids work.

7 min read · Updated

In NYC you make an offer by emailing the listing agent (or having your own agent email them) with your price, down payment, financing and timing, plus a pre-approval or proof of funds. In normal NYC practice, even an accepted offer isn't treated as binding until both sides sign a formal written contract, usually a week or more later after your attorney reviews the building.

That gap between "accepted" and "in contract" is the single most confusing part of buying in New York. Here's how the process works, what to put in your offer, and how bidding rounds play out.

At a glance

How offers are made
Email to the listing agent
No standard offer form; there’s no deposit with the offer
When it becomes binding
When the contract is signed
NY’s statute of frauds requires a signed writing; in practice that means the formal contract
Usual contract deposit
Often 10%
Paid at contract signing, held in escrow by the seller’s attorney
Mansion tax
1% at $1M+
Paid by the buyer; factor it in when you bid near $1M

Before you offer

Have these ready so you can move the day you find the place:

  • A pre-approval letter for a loan amount that fits the price. The CFPB notes that lenders use "prequalification" and "preapproval" differently and neither is a guaranteed loan offer, but a preapproval based on verified documents carries more weight with sellers. See mortgage pre-approval.
  • Proof of funds for the down payment and closing costs (a recent statement, with account numbers hidden).
  • A real estate attorney lined up. The seller will ask for your attorney's contact in the offer. Read what a real estate attorney does.
  • Your ceiling price, worked out with the home affordability calculator and NYC closing costs.
  • A building check. Look up violations, complaints and recent sales on Roofy's building lookup and NYC sales.

Know who the agent represents. Under New York's agency disclosure law (RPL §443), a seller's agent must give you a disclosure form at your first substantive contact. The listing agent works for the seller. If one brokerage represents both sides, both buyer and seller must give informed consent in writing. For how buyer-agent pay works now, see buyer broker agreements after the NAR settlement.

What to put in your offer

Offers are usually short, written emails. Clarity matters more than length. A complete offer covers:

The parts of an NYC offer email
ItemWhat to sayWhy sellers care
PriceA specific numberObvious, but not the only factor
Down paymentPercentage and dollar amountBigger down payments look safer, and co-op boards set minimums
FinancingLoan type and amount, or all cashSignals how likely the deal is to close
ContingenciesMortgage contingency (yes/no), any othersEach one is a way out for you
TimingTarget contract signing and closing datesSellers may be buying elsewhere
AttorneyName, firm, email, phoneThe seller’s attorney sends your attorney the contract
AttachmentsPre-approval, proof of funds, a short financial summary for co-opsLets the seller compare offers fairly

For co-ops, sellers know the board must approve you, so they may ask for a basic financial statement up front. Check co-op financial requirements and run the co-op board approval calculator before you bid.

From accepted offer to signed contract

    Your attorney does due diligence

  4. 4

    You negotiate the contract terms

  5. 5

    You sign and pay the deposit

Best and final rounds

When several buyers want the same apartment, the listing agent may ask everyone for their "best and final" offer by a set deadline. It's a sealed-bid round: you get one chance, and you usually won't learn the other bids. A few practical points:

  • Price is one factor. A seller may take a slightly lower offer with more cash down, no mortgage contingency, or a stronger co-op board package.
  • Only promise what you can deliver. Dropping your mortgage contingency to win can put your deposit at risk if the loan falls through.
  • Ask what matters to the seller. A quick or flexible closing date can matter as much as money.
  • "Final" isn't legally final. Until a contract is signed, the seller can come back for more, and you can still withdraw.

When a deal falls apart before contract

Because nothing binds until signing, deals can collapse late: another buyer offers more, the seller changes their mind, or your attorney finds a problem in the building's financials. You haven't paid a deposit, but you may have spent money on attorney review or an inspection. Reduce the risk by moving quickly, staying responsive to your attorney, and asking the listing agent to confirm in writing whether the seller is still showing the apartment.

If you're both buying and selling, plan the order of your contracts carefully; see buying and selling at the same time.

Next steps

Once you're in contract, follow the contract-to-closing timeline, prepare your co-op board package if needed, and use the closing day checklist at the end.

Statute of frauds (GOL 5-703(2)): a contract for the sale of real property is void unless the contract or a note or memorandum of it is in writing and subscribed by the party to be charged; wording softened so we do not claim an email can never bind. Mansion tax 1% at $1M+ paid by buyer confirmed on NYS Tax transfer tax page. RPL 443: seller’s agent gives the agency disclosure at first substantive contact; dual agency needs written informed consent of both sides. CFPB: prequalification and preapproval letters are not guaranteed loan offers. Mansion tax 1% at $1M+ paid by buyer. Deal-sheet contents and best-and-final process describe common NYC practice, not law; practice varies by brokerage.
